Was skeptical but I am impressed. It does start to rust after a while, nothing so serious though but, annoying still. You don't entirely need to drill down the bolts. Hammered it in the first time before I could drill it down and it held just fine.We have a 1yr old, 80sh lbs German Shepherd which should explain enough. He wouldn't hurt himself trying this but when he had the moments of too excited and full on running, this never pulled up or struggled to stay in. AFTER TIME though, you will…

I used my power drill and it worked beautifully. It is so secure its almost like it is attached to concrete rather than screwed into my yard.I have an 80 pound dog and there is no way he (or even I) could pull this out of the ground.I like that it isnt high also. The low profile makes it so I can mow over it without hitting it with blades of the mower.
